Thermal and hysteretic magnetic properties of La2 /3 Ca1 /3 MnO 3 nanoparticles were studied using Monte Carlo simulations, with emphasis on the inuence of anisotropy. In this work, several nanoparticle sizes ranging from 2.32 nm to 11.58 nm were analyzed and their properties were compared to those of the bulk material. The magnetic behavior of the material was modeled using the three dimensional Heisenberg model with nearest neighbor interactions. Furthermore, both uniaxial and Néel anisotropies were considered for core and surface magnetic sites respectively. Deviations in the critical temperature and coercive eld were observed for nanoparticles when compared with those of the bulk material. In addition to these properties, the special spin congurations that arise from the competition between the exchange, anisotropy and external magnetic eld were also studied. All these eects are interpreted in terms of the surface properties such as the Néel anisotropy and the decrease in the coordination number.
